PATENT OFFIc ROTATING STEAM-ENGINE.

SPECIFICATION forming part of Letters Patent No. 739,805, dated September 29, 1903.

Qpplication filed May 26, 1903 Serial Nol58,894. (No model.)

To all whom it may concern.-

Be it known that I, HANS'WILLIAM'JXN- DREAS ANDERSEN, a citizen of the Kingdom of Denmark, and a resident of Vejle, Denmark, have invented certain new and useful Improvements in Rotating Steam-Engines, of which the following is a specification.-

The present invention relates to improvements in a rotating steam-engine through placing the piston in such a manner as to give it a movement at a right angle with the main shaft, by which means it is possible to secure a better tightening between the piston and the cylinder than ordinarily obtained in other similar rotating steam-engines, and through giving movement to the slide-valve by the means of an eccentric controlling the feeding in connection with the piston.

In the accompanying drawings is shown in Figure 1 a section through the cylinder and slide-valve at a right angle with the shaft, and in Fig. 2 at a right angle with this a longitudinal section through the shaft.

a, is the cylinder in one piece with its bottom molding. The cylinder is closed by the two side pieces b and c, screwed onto it, and which are both forming-beds for the main shaft (1, on which is wedged the pulley e.

The shaft (1, which is made of steel, is in solid connection with a body formed by two large cylinders f and 91, having an outer diameter of about the same length as the inside diameter of the cylinder a, and a smaller cylinder h placed between them. 7 Between the cylinders a and h is thereby formed the steamchamber bounded by f and g. In the cylinder h is a cylindric recess i, which is continued in a minor cylindric recess 3'.

k is the piston, with a guiding-pivot Z turning toward the shaft. Between this and the bottom of the recess 3 is placed a screwspring m, which is tending to'hold the sliding planes of the piston pressed firmly out against the cylinder a. The piston in the execution shown in the drawings is cut off level at the side on which the steam works; but other shapes may be given to it, according to the intended speed of the engine.

On the outside of the cylinder h is screwed a piece it, which inside has the shape of the cylinder h and the following curved surface of the piston 7c, in such a manner, however,

as to leave a small intervening space between it and the piston is in order to allow the latter to move freely, and outside is a cylinder the guiding curve of which is forming part of a spiral.

In a recess 0 on the cylinder at moves a cylindric slide p. The slider-box is closed at the top with the cover g, which has a boring for the guiding-rod '2" of the slider. Around this is laid a screw-spring s, which at its lower part is pressing against the slider and at its upper part against a shoulder 25, fixed in the cover q, and thus tending to force the slider downward. In the slider is made a canal u for the ingress of the steam and an eduction-canal 'v, and in the slider-box o are formed corresponding holes for the tubes, through which the steam is alternately let into and away from the slider-box. On both sides of these tubes are placed common valves or cocks. The cock on the exhaust-tube of the slider-box will generallyremain shut and is only opened when the pressure during the up ward movement of the slider would be too great, and thereby cause a too great friction between the slider and the eccentric it, what might happen within the first few minutes after the setting in motion of the engine on account of the waste water that will immediately be gathering there. On the cylinder is an exhaust-opening a: for the exhaust-steam.

In the cylinders f and g are tightening-rings 1; but for the rest are found on the engine fly-wheels, regulators, packings, lubricators, (he, of ordinary constructions, which are not, however, shown in the drawings.

The engine'works in the following manner: The steam is led through the steam-pipe into the canal to of the slider and then works on the plane side of the piston, which causes the piston to be turned in the direction indicated by the arrow in Fig. 1. When this takes place, the slider will be lifted. by the eccentric it, sooner or later, according to its peripheric extension, thus producing a lower or higher degree of filling and shut out the steam. When the piston has passed the bottom of the slider, a smaller portion of which is cylindric, the slider will again by means of the spring 5 be pressed downward, and thereby open up for the steam.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent-- V v 1. In a rotary steam-engine, a cylinder a, a main shaft cl, a body adapted to move in said cylinder a formed in solid connection with the main shaft, said body consisting of two large cylinders fand g and a smaller cylinder h between them, a recess in said cylinder h, a piston therein, an eccentric-ring n partly surrounding the cylinder h and the piston and a slide operated by said eccentric, substantially as described.

2. In a rotary steam-engine, a cylinder a, a main shaft 01, a body adapted to move in said cylinder, and formed in solid connection with the main shaft, said body consisting of two large cylindersf and g and a smaller cylinder it between them, a recess in said cylinder h,

my invention I havesigned my name in pres- 3o ence of two subscribing witnesses.
